Ask HN: What open source projects need help?

Let's match open source projects that need help with developers looking to contribute. Think of this as "Who's Hiring" but for open source - a monthly thread to surface interesting projects that could use more hands.

Please include: Project name and description (if not widely known); Tech stack; Areas needing help (DOCS, CODE, DESIGN, etc.); Level (BEGINNER-FRIENDLY if applicable); Email address or other means of contacting you.

Ground rules:

Post only if you maintain/run the project

One post per project/suite

No commercial recruitment

No thread complaints

Developers: Only reach out if you actually want to contribute.
